Abstract

The research was conducted in Ayuhulalo area, which is located in the western part of Gorontalo Province, precisely in Tilamuta Sub-district, Boalemo Regency. The geomorphology of the research area is dominated by hilly to mountainous areas. The purpose of this study is to determine the characteristics of the landscape in the study area, determine Geomorphological units, and identify the type of constituent lithology in each Geomorphological unit with a remote sensing analysis approach based on DEM (Digital Elevation Model) SRTM (Shuttle Radar Topography Mission) data and field observations to identify the lithological conditions of the study area. The method includes aspects of geomorphology such as morphography, morphometry, and morphogenetics. The geomorphology of the study area consists of lava flow hills unit with porphyry andesite and porphyry dacite as the constituent lithology and pyroclastic flow hills unit where volcanic breccia is the constituent lithology.

Abstract

Geotourism emphasizes the beauty, uniqueness, rarity and wonder of natural phenomena as an impetus for the development of geology-based tourism. The many variations in geological aspects fulfill the potential geodiversity value in the area. The aim of this research is to identify and assess the potential for geodiversity in Oluhuta Village. The research location has coordinates 0° 25' 0" - 0° 27' 0" N and 123° 8' 30" - 125° 10' 30" E. There are several research methods used in the form of field observations, laboratory research, and processing studios. The geological data obtained includes lithology, geomorphology and assessment of geodiversity aspects. The results of the research show that the location of the research area has lithology namely reef limestone and geomorphology namely reef terrace plains. The research area has a site called the Lautan Terangkat Site. This site has geological components including rocks and natural landscapes. Lautan Terangkat site have several assessment criteria with a total number and scientific assessment classification. Scientific value assessment is classified as medium, the educational value assessment is classified as high, tourism value assessment is classified as medium, and the assessment of degradation risk value is classified as low.

Abstract

Solar energy is renewable and environment friendly and has been widely used in electricity generation and thermal energy through photovoltaic thermal (PVT) system. This system is beneficial in terms of maximum energy generation and cost of usage. The growing concern on energy sources and their usage has increased the significance and demand for PVT collectors. A PVT air collector consists of a PV panel and a thermal collector system. In PVT air collector, electricity and thermal energy are generated simultaneously. This review focuses on efficiency and energy modelling for PVT air collector with extended heat transfer area. Findings of this review indicated that PVT air collector with extended heat transfer area produced PVT efficiency higher than conventional PVT air collector. The thermal efficiency of PVT air collector for with and without extended heat transfer area are 21-83% and 12-70%, respectively, which the improvement of thermal efficiency is 15.7-42.8%.
